The correct equation representing the time Bailey spends in the weight room each week is 2w=3. By solving this equation, we find Bailey spends 1.5 hours in the weight room each week.

The question tells us that Baily spends 3 hours each week playing soccer and this is two times the amount of time she spends working out in the weight room. We can represent the time she spends in the weight room as w. So, the question gives us the equation 2w=3. Since 2 times what number gives us 3, we can solve for w by dividing both sides of the equation by 2. When we do this, we have w=3/2, which means Baily spends 1.5 hours in the weight room each week.

Answer:

The measure of the angle is [tex]30\°[/tex]

Step-by-step explanation:

Let

x-----> the measure of the angle in degrees

we know that

The measure of a complete circle is [tex]360\°[/tex]

so

by proportion

[tex]\frac{360}{1}\frac{degrees}{circle}=\frac{x}{(1/12)}\frac{degrees}{circle}[/tex]

[tex]x=\frac{1}{12}(360\°)[/tex]

[tex]x=\frac{360\°}{12}[/tex]

[tex]x=30\°[/tex]

An angle that represents 1/12 of a circle measures 30 degrees. We found this by understanding that a full circle is 360 degrees and then multiplied 1/12 by 360.

The question is asking for the measure in degrees of an angle that represents 1/12 of a circle. As we know, a circle consists of 360 degrees next we measure the angle just like when we are measuring the angle in the sky. To find the angle, we can use a simple proportion. Since the whole circle is 360 degrees, we know that 1/12 of the circle will be equal to 1/12 of 360 degrees.

So, the calculation will be like: 1/12 x 360 = 30 degrees. Therefore, an angle that represents 1/12 of a circle measures 30 degrees.

Answer: [tex]b=10^3[/tex]

Step-by-step explanation:

You know that there are 10 blueberries in each muffin. There are 10 muffins in each box and the total number of boxes is 10.

Then, to calculate the total number of blueberries, you need to multiply the total number of boxes by the number of muffins in each box and multiply this by the number of blueberries in each muffin.

Let be "b" the total number of blueberries. Then:

[tex]b=10*10*10[/tex]

By the Product of powers property:

[tex]a^m*a^n=a^{(m+n)}[/tex]

Then you can write the expression:

[tex]b=10^3[/tex]

To find the equation of the perpendicular bisector, find the midpoint of the line segment and determine the slope of the perpendicular line.

To find the equation of the perpendicular bisector of a given line segment, we need to find the midpoint of the segment and then determine the slope of the perpendicular line. Let's denote the coordinates of the endpoints of the line segment as (x1, y1) and (x2, y2). The midpoint of the segment can be found using the formula:

M = ((x1 + x2) / 2, (y1 + y2) / 2)

The slope of the perpendicular line can be found using the negative reciprocal of the slope of the given line segment:

Perpendicular slope = -1 / slope of given line segment

Once we have the midpoint and the slope of the perpendicular line, we can use the point-slope form of a linear equation to write the equation of the perpendicular bisector:

y - y1 = perpendicular slope * (x - x1)

Answer:

Step-by-step explanation:

If y = 2x + 1, then dy/dt = 2(dx/dt).

If y = 2x + 1, then y = 2(40) + 1 when 40 is substituted for x.  y = 81.

(a) if dx/dt = 3, find dy/dt when x = 4:

       Replacing dx/dt with 3 in dy/dt = 2(dx/dt) yields dy/dt = 2(3) = 6.

(b) if dy/dt = 2, find dx/dt when x = 40:

        Replacing dy/dt with 2 in dy/dt = 2(dx/dt) results in 2 = 2(dx/dt), so dx/dt must be 1.

First, you differentiate the given function. Next, apply the chain rule which states dy/dt = dy/dx * dx/dt. Substitute the known values to find dy/dt. For the second part, rearrange the chain rule to find dx/dt = dy/dt / dy/dx and substitute the known values.

This question deals with the basic application of the chain rule in differentiation. The given function is y = 2x + 1, where both y and x are functions of t. You are supposed to determine dy/dt and dx/dt.

(a) First, differentiate y = 2x + 1 with respect to x to obtain dy/dx = 2. According to the chain rule in calculus, dy/dt = dy/dx * dx/dt. Substituting the known values from the question, we have dy/dt = 2 * 3 = 6 when x = 4.

(b) For dy/dt = 2, you need to rearrange dy/dt = dy/dx * dx/dt to find dx/dt = dy/dt / dy/dx. As dy/dx = 2, you can evaluate dx/dt = 2 / 2 = 1 when x = 40.

The equation [tex]4x ^ 2 + 5y ^ 2 = 20[/tex] has center in (0,0).

But the transformation [tex]T(5, -6)[/tex] shifts the center of the equation to the point (5, -6).

Therefore, when applying [tex]T(5, -6)[/tex] we will have the following equation translated.

[tex]4(x-5) ^ 2 + 5(y - (-6)) ^ 2 = 20[/tex].

Simplifying we have:

There are 2.4 hours of infomercials in a 24-hour day if they account for 10% of the daily broadcast.

The question asks us to calculate the amount of time designated for infomercials in a 24-hour day if they make up 10% of the day's broadcast. To find the answer, we can use the basic percentage calculation.

To calculate 10% of a day, we need to know that a day has 24 hours. So 10% of 24 hours is calculated as follows:

(10/100) × 24 = 2.4

Therefore, there are 2.4 hours of infomercials in a 24-hour day.

Solving the system of equation, we get Option (C) (2,-1).

The equations given are 2x - y = 5 and 3x + 2y = 4.

To find the point which solves the two equation, we have to satisfy the given x and y coordinates of the point on the given two equations.

Checking all the other Options, it does not satisfies except Option (C).

Checking the point (2,-1) on the first equation 2x - y = 5 , we get 5 in the left hand side of the equation.

Again checking the point (2,-1) on the second equation 3x + 2y = 4 , we get 4 in the left hand side of the equation.

Therefore the coordinates (2,-1) (Option C) satisfies both the equation which is the required solution.

Answer:

The value of x = -0.17

Step-by-step explanation:

∵ [tex]2e^{8x}=1-e^{4x}[/tex]

Let [tex]e^{4x}=y[/tex]

∴ [tex]e^{8x}=y^{2}[/tex]

∴ 2y² = 1 - y

∴ 2y² + y - 1 =0 ⇒ factorize

∴ (2y - 1)(y + 1) = 0

∴ 2y - 1 = 0 ⇒ 2y = 1 ⇒ y = 1/2

∴ y + 1 = 0 ⇒ y = -1

∵ [tex]y=e^{4x}[/tex]  

Note: [tex]e^{4x}=-1[/tex] ⇒ refused

         ([tex]e^{ax}[/tex] never gives -ve values)

∴ [tex]e^{4x}= 1/2[/tex] ⇒ insert ln in both sides

∵ [tex]ln(e)^{ax}=axln(e)=ax[/tex] ⇒ ln(e) = 1

∴ 4xln(e) = ln(1/2) ⇒ 4x = ln(1/2)

∴ x = [ln(1/2)]/4 = -0.17

Answer:

155 lbs.

Step-by-step explanation:

69.75 g of protein divided by 0.45= 155

Answer: He weighs 155 lbs.

Step-by-step explanation:

Since we have given that

Amount of protein he used = 69.75 g

Factor = 0.45

We need to find the weight of an individual.

So, Weight of an individual is given by

[tex]Weight\times factor=Protein\\\\Weight=\dfrac{Protein}{Factor}[/tex]

[tex]=\dfrac{69.75}{0.45}\\\\=155\ lbs[/tex]

Hence, he weighs 155 lbs.

Looks like the limit is

To find the sale price of a $384 skateboard with a 24% discount, convert the paid percentage to a decimal (76% to 0.76) and multiply with the original price, resulting in a sale price of $291.84.

To calculate the sale price of a skateboard originally priced at $384 with a 24% discount, we first need to determine what percentage of the original price will actually be paid. Since the discount is 24%, that means 76% of the original price will be paid (100% - 24% = 76%). To convert this percentage to a decimal, we divide by 100, getting 0.76.

Next, we find the sale price by multiplying the original price by the decimal form of the percentage paid:
$384 × 0.76 = $291.84 as the sale price of the skateboard.

The volume of a sphere with a radius of 4 centimeters is calculated using the formula V = (4/3)πr³. Substituting 4 cm for the radius and 3.14 for π, the volume is approximately 268 cubic centimeters.

To calculate the volume of a sphere with a given radius, you can use the formula V = (4/3)πr³, where V represents the volume and r is the radius. In our case, the radius is 4 centimeters. Substituting the values into the formula gives us V = (4/3) * 3.14 * (4 cm)³.

Performing the calculation: V = (4/3) * 3.14 * 64 cm³ = 267.94666666666666 cm³. Therefore, the volume of the sphere is approximately 268 cm³ when rounded to a whole number.
